This study aims at developing an individual-tree distance-independent growth simulation model. The simulation model was designed to integrate four equations, needed to estimate crown ratio, potential diameter growth, modifier and mortality rate, into a user-friendly interface modules. The model was also tried to predict growth of a 17-year-old Pinus koraiensis stand for 10 years from age 20 to 30. The results showed that the average DBH of the stand increased by 4.1 cm, stand volume increased by 109.5§©/ha and the percentage of the volume increase by Pressler equation was about 7.4. Stand density decreased by 598 trees/ha or 38% due to mortality.
Key words: individual-tree distance-independent growth model, Pinus koraiensis, performance of simulation model
